24. INSTALL CAMSHAFTS

NOTICE:
Keep the camshaft level while it is being removed.
The camshaft thrust clearance is very small and
failing to keep it level could crack or damage the
cylinder head journal surface, which receives the
thrust force. This could subsequently lead the
camshaft to seize or break. Perform the following
steps to avoid such problems.

(a) Set the crankshaft position.

(1) Using the crankshaft pulley set bolt, turn the

crankshaft, and set the crankshaft set key in
the left horizontal position as indicated.
NOTICE:
Setting the crankshaft at the wrong angle
could cause the piston head and valve head
to come into contact with each other when
the camshaft is installed. This could cause
damage, so always set the camshaft at the
correct angle.

(b) Apply new engine oil to the thrust portion and

journal of the camshafts.

(c) Install the camshafts of bank 1.

(1) Place the 2 camshafts on the cylinder head RH

with the No. 1 cam lobes facing as shown the
illustration.

(2) Install the 8 bearing caps in their correct

locations.

(3) Apply a light coat of engine oil to the threads of

the bearing cap bolts.
